When the Particle System has PointLight setting and it comes out of camera frustum area, the Particle System Light doesn't light

Reproduction steps:
1. Open the attached file;
2. Open the scene 'TestOffScreenLightParticle';
3. Change Main Camera Rotation of X or Y axis;
4. Observe changes in Game window;

Actual result: the Point Light doesn't light when it comes out of camera frustum area.
Expected result: the Point Light should light.

Workaround: When the Point Light is a separate gameobject, everything works correctly (PointLight.gif). But the issue happens when the Point Light is set in the Particle System (ParticleSystemLight.gif).

Reproduced with: 5.5.0b1, 5.5.0f1, 5.5.0f3, 5.6.0a6

Not reproducible in older Unity versions than 5.5.0b1 because the Particle System doesn't have Light settings.
Also, not reproducible in 5.6.0b1 because the Point Light Intensity settings are different in this version.
